Electronic filing requirement: LLP documents must be digitally filed and authenticated, with rectification and invalidation procedures enforced. Every form, application or document required under the Act for an LLP must be filed in PDF and authenticated by a partner or designated partner using a valid digital signature certificate of Class II or Class III. The Central Government shall maintain a secure electronic registry and portal for storage, public access on payment of fees, and electronic issuance of certificates and communications; manual issuance is permitted where electronic issuance is infeasible. The Registrar will examine filings, require rectification within aggregate periods not exceeding thirty days, and may reject or mark as invalid filings not corrected, with invalid filings requiring fresh filing and fees.
